Nuts about Nets (that’s the company name…) WifiMETRIX is a dual band WiFi diagnostic tool used to analyze, monitor and troubleshoot Wi-Fi networks. The handheld device implements two main features:
- AirHORN RF signal / channel generator that transmits RF signals for each of the Wi-Fi channels, and aids in testing Wi-Fi antennas, RF shields and wireless networks.
- WiFiPROBE for per channel’s throughput analysis
The device operates in standalone mode and does not need to associate with the access point to perform the functions.
WifiMETRIX technical specifications:
- Dual-band 802.11 Wi-Fi chip
- Antennas / connectors
- Dual-band antenna for 2.4 and 5.x GHz ISM bands
- Standard 50 ohm SMA antenna connector
- 50 ohm SMA terminator to protect antenna connection
- SMA terminator (dummy load) also used for calibrating the device
- Functions
- AirHORN channel / signal generator functionality (packet injection)
- WifiPROBE channel analyzer functionality
- Display – 128×64 built-in LCD screen
- USB – 1x micro USB port for charging
- Dimensions – 210mm x 155mm x 39mm (Solid aluminum case plus silicon rubber boot protector)
- Weight – 425 grams
- Certifications – CE and FCC compliance
The AirHORN feature can be used to test WiFi antennas & amplifiers, test the effectiveness of RF shield designs, stress-test wireless networks, align directional Wi-Fi antennas, quick evaluation of receiver performance, and locating Wi-Fi dead spots.
The WifiPROBE feature can be used to detect presence of RF interferences, determine whether performance can be improved by using a different channel, quantify expected change in performance that would result from using a different channel, configure Wi-Fi networks with the goal of improving throughput performance, and as a tool to help placing Wi-Fi devices into a location offering the best performance.
